DC Motors

Shunt series compound dc motors
"motco" make dc motors are available with different performance characteristics and accordingly are classified into shunt series & compound motors.
Dc motors have definite applications in today's industry. Each type offers specific characteristics and strengths, depending on the task at hand.
Shunt wound motors are the most widely used as they have a linear characteristic of voltage & torque.
Shunt motor has more constant and controllable speed over various loads.
Series wound motors are used for high starting torque applications. Series motor has greater torque capabilities
compound wound motors are used for mixed load applications.
The above two desirable characteristics can be found in the same motor by placing both a series field and shunt field winding on the same pole. Thus we have, the compound motor.
The compound motor responds better to heavy load changes than a shunt motor because of the increased current through the series field coils. This boosts the field strength, providing added torque and speed.
